Used Golf Cart Batteries

Are you thinking of replacing your batteries with used golf cart batteries?

Or are you considering buying a used electric golf cart with used and not new golf cart batteries? Typically, golf cart batteries are good for 4 years and with good maintenance up to 7 years. . So you will want to know:

√ How old the batteries are and

√ What kind of maintenance was performed,

√ How they were used and

√ How they were stored.

Check to see how much water is covering the batteries or if they've been allowed to go dry.

Testing Used Golf Cart Batteries

Also you can check the batteries yourself with a battery hydrometer to see if they are weak. Two important reminders:

1. Be sure the batteries are fully charged or you will get an inaccurate reading.

2. Do not perform this specific gravity test right after adding distilled water to the cells.

The battery hydrometer has 3 colored sections - green, white and
red. The green indicator means that the batteries are strong, white
means they are OK, and red means a very weak battery.

Always wear protective clothing, gloves, and eye wear when
working with lead acid batteries. Remove the cell caps. You will need
to individually test each cell.

This tester is a small investment and every golf cart owner should have one - get one at Amazon for $10 and free shipping here:

Replacing with a Single Used Battery

Ideally, when it comes time to replace your golf cart batteries, you want to replace them all with new ones.

If you find that one of your batteries has gone bad, do not
replace with one new battery. If you do, the weaker batteries will take
power from the new battery to equalize the rest of the set and the new
battery is drained.

You can consider replacing the entire pack of batteries with used batteries if they are all about the same age and usage level.

Recondition Used Golf Cart Batteries

Terry from Thermoil.com shares with Golf Carts Etc. readers what can
be done to recondition or rejuvenate weak golf cart batteries.

Golf cart batteries weaken when lead sulfate builds up on the plates.

It forms a hard crust that interferes with the exchange of sulfuric acid going in and out of the plates.

Find out why this happens, how to prevent it and what to do if your batteries are no longer holding or keeping a charge.
